I agree with elsamuri, CFLs work, but it is a challenge to get enough photons to the leaves. For happiest plants I want about half the intensity of midday sun, that requires a lot of CFLs. And CFLs are half as efficient as HPS... that means more heat and more electricity. CFL is OK for 1 or 2 small plants. If you are growing more maybe you can find a cheap HPS, all the commercial agriculture growers use them worldwide,so they have to be available.
I had 200 actual watts of CFL on my HBSS, I think she could have used twice as much light!
Thanks Bubba for the info !! the problem over here is the electricity cost .... HPS eats lots of Kw ..... im thinking to grow only 1 plant ... and already did my homework about CFL's and for what i saw and read ... if you get the right onces with the right lumens .... you can get pretty nice plants. Im sure HPS and LED's are gonna give you better plants .... but for me right now its about Electricity cost, i already put my seed on paper towels. As soon as she shows up, ill start a journal as well !!
